Web2 years ago. The focal length of a concave mirror is also negative. That would give us -1/f = -1/v -1/u which is the same as 1/f = 1/v + 1/u. So,the thin lens formula works for both convex and concave lens.

WebFind the distance from the object to the lens, and the distance of the image to the lens, by subtracting out the distance from the lens to the eye. Now apply the thin lens equation to determine focal length. Recall that if the image is on the same side of the lens as the object, then image distance is negative.
